The ARM MK7 Bi-Cooler Piping Upgrade allows you to run the ARM MK7 FMIC with the OEM intercooler, or any upgraded OEM location intercooler that fits the OEM charge piping. The ARM MK7 Bi-Cooler Upgrade is the ultimate solution to boost the performance of your MK7's charge-air cooling system. The ARM MK7 Bi-Cooler Upgrade features a unique dual-cooling setup that significantly improves the heat dissipation of your Gen 3 EA888, allowing for lower IAT's, higher power output and increased cooling efficiency.
Made from 6-Layer Steel Wire Reinforced Silicone, the ARM MK7 Bi-Cooler Piping Upgrade can handle over 50psi, and anything you can throw at it. To secure the boost, the ARM Bi-Cooler Kit uses constant-tension T-Bolt clamps to prevent any loosening over time.
The ARM MK7 Bi-Cooler Piping Upgrade maintains a consistent 2.5" diameter throughout the entire system to maximize volume while maintaining charge-air velocity. In testing we found the ARM Bi-Cooler Setup to be incredibly effective, pairing the ARM MK7 FMIC with just the OEM intercooler we were able to see IAT's around only 13 degrees above ambient.

A true turtleneck that retains a snug high neck.
Color: White, Size: X-Large
I've found this brand to have gotten better over the years as far as offering the American market what it needs in terms of realistic sizing. I only wish they'd realize that there are a lot of us who are long in the back and arms where my only choice is to go a size up and sacrifice a slim fit for sleeves that are long enough plus a back that doesn't go up past my waist just because I reach up for something, that and I like to be warm. So these are such nice quality turtlenecks that it's hard to complain about but maybe the company will read this. The snug neck stays up is plus number one since that's why I'm buying a full neck. They come with very nice weaves in the fabric, good enough for casual or formal wear. Finally the warmth you seek is there but I've worn them in what most would think isn't the right temp for a turtleneck. Also they have them in white! Yes, a lot of others just don't for reasons I can't fathom, and the pic you're seeing is accurate, these will form to your shape without being ridiculously thin material. Several washes later and they are as fine a garment as when I first wore them. I've only found one other brand that compares to these but it's much more expensive, COOFANDY is affordable in these times of expensive everything. Warm but also a lightweight shirt, I've gotten them really dirty with actual dirt and it washes out so well you'd never know it. Don't let my taking off one star stop you, try one yourself and you'll be coming back for more.
